Insecticides control pesky insects that damage your garden, landscape plantings, or lawn turf. Effective and responsible control begins with proper pest indentification. Contact one of our staff to help. Insecticides generally work in two ways. Some are effective only when coming in contact with the insects. Others are systemic insecticides meaning that they are absorbed into the plant tissue and act as an insect deterrent. River Valley also stocks product safe for use on food-producing plants like fruit trees and vegetables. Some biological controls are available, too.
